same problem ! but i thing there are something wrong in the extractor , when i push on the motion driver button > telemetry plugin > i should see a list of all my game's plugin (official ) but i have only for : falcon 4 , r.d.grid, Kartracing, rbr.
I am not able to check the box for enabling plugin developper !
i found something !

i am able to check the enable plugin developper, i had to check a plugin first , I check falcon 4 for fun and > Try send Data and i have the named force written in the converter, then..... now i know it's a plugin detection or installation in the extractor but i don't know why that works with force-sender
